It's all written above, "If you have few bucks to spare, please consider purchasing the icon theme to support the project and show that you appreciate the work and time spent into making the icon theme."

Pretty good stuff. There's a not-insignificant number of icons missing, but as said this is a WIP (and hasn't been updated in seven months at that) so I guess it works

Is there any chance of there being some application icons that are just normal (not circle or square or what have you) in this iconset?Ideally it would be only icons that look out-of-place when put next to this set like gedit, terminal, calculator etc and not ones like firefox or gimp.

I like the overall design of Numix, but personally I find it a bit irksome when an iconset tries to stuff everything into an arbitrary shape. :/
